           Summary: 2d save of "Save As foo.pcap" "Save As foo.pcap"
                    sequence fails

          Severity: Minor
          Priority: Low

The following sequence fails on Windows Wireshark:

   a. Start Capture/capture some packets/Stop capture;
   b. "save as foo.pcap" (will be OK);
   c. "save as foo.pcap" again (will fail somewhat weirdly with a gtk popup
window  indicating "file exists" after the Windows "save as" popup & etc).

The reason is that the second "save as" fails when trying to unlink foo.pcap
before saving it via cf_save. (See win32_file_dlg.c and file.c). The unlink
fails because the file is still open from the first call to cf_save).

The problem also shows up when doing a "file open foo.pcap" and then a "file
save as foo.pcap".

This would seem to be a rather "special case" which I'm not sure how to
address;  Somehow detect that "save as <filename>" is to the currently open
<filename> ?
